Hi, it’s Clément! 👋
As a software engineer at Rothesay in London, I’m building fast tools in Python and Rust to make other developers more productive. Before that, at Paxos, I was building a smart order router for crypto markets in Rust. And before that, I was part of the DDoS protection team at Cloudflare, using technologies like eBPF or Rust. I presented some of my work at the Linux Plumbers Conference 2020. Previously, I worked on non-intrusive performance analysis at the SnT, a lab part of the University of Luxembourg. More on my CV.
In my spare time, I enjoy writing and contributing to open-source programs. I also blog mainly about performance and tools I use (like NeoVim, Hugo or SQLite). Some of my writing made it to the front page of HackerNews or Lobsters, sparking fruitful discussions in the comments. See the blog roll for my curated selection of blogs.

Let's Encrypt CAA Records with Caddy
A Man-in-the-Middle Attack I host my own instance of miniflux, an RSS reader. I do it as a hobby, I enjoy the learning opportunities that come along the way. One such opportunity presented itself in November 2023. Back then, a Man-in-the-Middle attack was reported against jabber.ru. You can go read the full details on that blog post, but let’s go over its main aspects. Without the attacker, a client connects directly to the jabber.ru server over TLS: ...
Cargo Info in Neovim, or How Simple Features Go a Long Way
TL;DR Open cargo info in Vim or neovim for the package under the cursor using these 4 lines of Lua. Cargo info Rust 1.82 was released a couple of days ago. It’s packed with improvements, but one in particular caught my eye. Cargo now has a info sub-command. It displays details about a package in the registry from the comfort of your terminal. Here is an example: $ cargo info lazy_static lazy_static #macro #lazy #static A macro for declaring lazily evaluated statics in Rust. version: 1.5.0 license: MIT OR Apache-2.0 rust-version: unknown documentation: https://docs.rs/lazy_static repository: https://github.com/rust-lang-nursery/lazy-static.rs crates.io: https://crates.io/crates/lazy_static/1.5.0 features: spin = [dep:spin] spin_no_std = [spin] note: to see how you depend on lazy_static, run `cargo tree --invert --package lazy_static@1.5.0` Vim and neovim generally composes well with other terminal tools. So how can we easily integrate cargo info and neovim? ...
